Revision history for File::Which.

0.05  Mon 24 Jun 23:06:45 CET 2002
    - Made sure the file wasn't a directory, as directories usually
      have x set.
    - made pwhich say so if it didn't find a file.
    - improve file searching: file doesn't have to be -x on MacOS,
      only -e. Same thing on DOSish, but only if the file extension is
      in PATHEXT (so we don't look for non-executable files that
      happen to be in PATH).
    - For DOSish, VMS and Mac, add current directory in front of path,
      as (on Win32) this one is searched first. (could someone tell me
      if this assumption is true on VMS and MacOS too?)
    - large updates to test suite: we now emulate executable files
      inside t/test-bin/. Like this we have more control. I hope
      this test suite will be better, but it is probably still
      shaky. Any reports would do me a lot of good.

    - Re-wrote some parts for more platform-specific code (Mac and VMS
      primarily). Thanks to Abigail and the PPT `which':
      http://www.perl.com/language/ppt/src/which/index.html
    - Removed the '~' handling: was probably broken anyway.
    - fixed a bug with pwhich -a where it would return the number of
      results instead of the results

0.03  Wed 24 Apr 14:48:50 CET 2002
    - Changed the '~' handling: last version was buggy, it needs to
      only replace it on Unix and if $ENV{HOME} exists, replacing it
      then with $ENV{HOME} (removes File::HomeDir dependency).
    - Added documentation to pwhich (you can run perldoc on it now)

0.02  Fri 19 Apr 02:52:15 CET 2002
    - Some documentation changes
    - Added where($short_exec_name) as an alias for
      which($short_exec_name, { all => 1 }).
      [Request from Jerrad Pierce <belg4mit (at) mit.edu>]
    - Added the which option --all. Other options just bloat everything.
    - Added `pwhich', perl-only replacement for `which'.

0.01  Sun 14 Apr 23:05:37 CET 2002
    - original version; extracted from DocSet. Only plain which() with
      docs and tests.
